Abstract

Hypophosphatasia (HPP) is associated with significant morbidity and mortality in pediatric patients. The disease also imposes a high disease-burden in adult-onset HPP. Asfotase alfa (AA) is the first-in-class, bone-targeted, enzyme- replacement therapy designated to reverse the skeletal mineralisation defects in HPP. A male newborn presented with extreme fontanel gap and respiratory distress. He was diagnosed with perinatal lethal HPP thus AA treatment was started. Serum alkaline phosphatase (ALP) levels increased as high as 12,700 U/L during treatment. Any side effect related to AA was not observed. AA may be a valuable emerging therapy for the treatment of HPP.
